Application led April 14, 1920.

To allwhomt my concern:

Be it known that I CHARLES E. PRICE, a citizen of the United tates, residing at San Diego, in the county of San Diego and State nof California, have invented certain new leaving internal combustion engines; third,

to provide a device of this class in which the exhaust vapor is caused to circulate 1 n opposite directions in said muffler and is retarded in its flow by reason of its counteracton; fourth, to provide a device of this classwhich is easy to disassemble and repair and, fifth, to provide a device of this class which is very simple and economical of c onstruction, durable, easy to install, applicable for use with the different makes of engines now in use, very eiiicient in its action and which will not readily deteriorate or get out of order.-

With these and other objects in view as will appear hereinafter my invention ycon` sists of certain novel features of construction, combination and arrangement of parts appendedclaims reference being had to thev accompan ing drawings and -to the characf ters of reference thereon which form a part of this application in which: v n

Figure 1 is a longitudinal sectional view of my muffler through 1-1 of Flg. 3; F 1g.2 is a sectionalview through 2-2 of Fig. 1 and Fig. 3 is a sectional view through 3-3 of Fig. 1.

substantially duplicates in form. They are provided with flanges 1a and 2, adapting them to be connected toexhaust conductorsl and are provided with frusto-conical shaped portions 1b and 2b and on the perimeter are provided with lugs 1c and 2 provided with holes adapted for the rods 4. In this case I have shown three, though it is obvious that there may be any number. Secured between the members 1b and 2b ositioned in the notches 1d and 2d is the cy indrcal casing 3. Mounted in this cylindrical casing 3 are the cone and frusto-conical shaped partitions 5 to 12 inclusive. It will be noted that the inlet openings in these frusto-conical mem-l bers decrease in diameter toward the outlet end of the muffler and that the outer diameter of these frusto-conical members decrease in diameter, thus providing for a propor-v tionate distribution ofthe exhaust vapors from the engine between the several frustoconical members. These frusto-conical partition members are supported by means of lugs a extending from said partitions and provided with holes through which the. rods 4 pass and mounted on said rods between the lugs a are separator sleeves .4a for holding said partitions in certain spaced relation and said rods 4 are threaded some distance from their ends and nuts 4b rovided for -supporting the several partitions so that they may be removed from the casing 3 in `their united form. Mounted on the face of these frusto-conical members toward the inlet of the muiler are a plurality of curved vanes which tend to direct the course of the exhaust vapors in its course outwardly toward the casing and outlet. It will be noted that'these vane members are positioned so f that the curves are in opposite directions on the alternate frusto-comcal members so that the exhaust is directed in opposite directions with each alternate frusto-conical member,

thus causing it to unite while passing in opposite directions, after passing through between the frusto-conical members and causing retardation of its iiow.l It will be noted that the cone member 12 has no opening and the remaining exhaust must pass around the same. Mounted in the outlet end is a frustoconical member 14 which is provided-with perforations to permit the exhaust vapors to pass through as well as permit a certain portion to ass through the opening.,` f

Though have shown and described a circulate in opposite directions in alternate4 layers, causing it to unite in its passage from between the partitions, causing retardation of its flow; that the openings 1n the several partitions are graduated, thus dis-v tributing the volume proportionately between the various artitions and providing additionalretardation through perforations near the outlet of the muffler thus providing for counteraction of the circulation of the exhaust vapors through the muflier.

Having thus describedmy invention what I claim as new and desire to secure by Letters Patent is:

1. A muffler for exhaust gases, including a casing, a pluralit of partitions therein provided with gra ually decreasing inlet openings centrally in said partitions and with gradually increasing outlet openings at the outer edge of vsaid partitions.

2. A muiller for exhaust gases, including a casing, a plurality of partitions therein provided with adually decreasing inlet openings centralyin said partitions, with gradually increasing outlet openings' at the outer edge of said lpartitions and curved vanes secured between said partitions positioned to direct the ases in opposite directions between thea ternate partitions.

3. A muiler for exhaust gases, including a casing, a pluralit of partitions therein provided with gra ually decreasing inlet openings centrally in said partitions and with gradually increasing outlet openings at the outer edge of saidpartitions and a perforate member in the outlet end of said casin 4. muler for exhaust gases, including a casing, a pluralit of partitions therein provided with lgra ually decreasing inlet openings centra y in said partitions, with gradually inereaslng outlet openings at the outer edge of said artitions, curved vanes secured between sai partitions positioned to direct the tween the a ternate partitions and a perforate frusto-conical member in the outlet end of said casing.

gases in opposite directions be- 5. A mulller for exhaust gases, including a cylindrical casing, inlet and outlet members for supporting said casing, a plurality of frusto-conical shaped partitions' w1 gradually decreasin inlet openings toward the outlet end of said casing and gradually increasing outlet openings toward said outlet end. f

6. A muiller for exhaust gases, including a cylindrical casing, inlet and outlet members for supporting said casing, a plurality of frusto-conical shaped partltions with radually decreasing inlet openings towar the outlet end of said ca sing and gradually increasing outlet openings toward said .outlet end and curved vanes mounted on one side of each of said partitions positioned with the curves in opposite directions on each alternate partition whereby exhaust gases arey conducted in opposite direction between the alternate partitions.

7. A muiiler for exhaust gases, including a cylindrical casing, inlet and outlet members for supporting said casing, a plurality of Jfrusto-conical shaped partltions with radually decreasing inlet openings towar the outlet end of said casing and gradually increasing outlet openings toward said outlet end, curved vanes mounted on one side of each of said partitions positioned with the curves in`opposite directions on each alternate partition whereby exhaust gases are conducted in opposite direction between the alternate partitions and a perforate frustoconical shaped partition in the outlet end of said casing.

8; A muiiler for exhaust gases, including a cylindrical casing, inlet and outlet members for supporting said casing, a plurality of frusto-conical shaped partltions with radually decreasing inlet openings toward the outlet end of said casing and gradually increasing outlet opemngs toward said voutlet end, curved vanes mounted on one side of each of said partitions positioned with the curves in opposite directions on'each alternate partition whereby exhaust are conducted in opposite direction between the alternate partitions, a `perforate frusto-conical shaped partition in the outlet end of said casin and rod means for connecting said cylindrical casing with the inlet and voutlet supporting members adapted to engage said partitions for supportin them in position.

In testimon whereoLI have hereunto set my hand at an Diego, California, this 8th day of April, 1920.
